Wilmut And Dr Unicellular Organisms
1,428 words
The biological definition of a clone is an
organism that has the same genetic information as
another organism or organisms ("Cloning", 1997).
From this definition and from information about
the science behind cloning, my current view on
cloning is that it is ethical. This statement
ignores information about how we can misuse
cloning and what consequences occur when the
procedure is unsuccessful. I currently do not
think cloning should be used until it is
perfected. I doubt however that we will a...

Rapid Expansion Blue Green
1,211 words
Up until 1947, it was believed that the Cambrian
Explosion marked the first true abundance of
multicellular life. However, this was discovered
to be untrue after Sir Douglas Mawson and R. C.
Spring mistakenly came across numerous "fossil
jellyfish" in the Ediacaran Hills while observing
what was originally believed to be sandstones
belonging to the lowest strata of the Cambrian. At
first, these finding were dismissed as "fortuitous
inorganic markings. " (AAS Biographical Memoirs. )

ter> The nature of DISEASE CAUSING ORGANISMS and
the mechanisms employed by man to combat these
organisms. What is disease? A disease is
a disturbance in the normal structure or function
of an organism, group of organisms or the entire
body. Diseases affect different organisms in
different ways, they may be temporary, they may be
chronic, or they may be terminal. They may even be
localized or widespread through an entire body.
Many diseases have been eradicated, but, some have
no cure....

Ecology The Study Of Plans Animals And Environment
1,134 words
Ecology is the scientific study of the
interrelationships of plants, animals, and the
environment. In recent years, the word has
sometimes been misused as a synonym for
environment. The principles of ecology are useful
in many aspects of the related fields of
conservation, wildlife management, forestry,
agriculture, and pollution control. The word
ecology (Greek, oikos, "house, " and logos, "study
of") is generally believed to have been coined by
Ernst HAECKEL, who used and defined it in 1869.

... ugh the changes occur gradually. Eventually a
point is reached at which the environmental and
species changes are minimal and species diversity
is high. This relatively stable community is
called a CLIMAX COMMUNITY. ECOSYSTEMS Many
ecologists study communities in the context of an
ecosystem, which includes interactions involving
mineral cycling, energy flow, and population
control. The study of ecosystems facilitates a
functional approach to ecology. One of the major

The Biological Importance Of Water
1,055 words
Generally, the main biological importance of water
is that life cannot exist without it. In fact on a
percentage basis, the majority of any organism is
comprised of water. Additionally, it is believed
that life first originated in the bodies of water
on the earth. The importance of water is seen in
such third world countries as Kenya. Where the
inhabitants are forced to drink water so dirty and
contaminated that they know it might kill them.
However they still drink it because its essential

Type Of Cloning Cloning Of Humans

Cloning Cloning as a concept has been recently
launched by scientists and adopted by contemporary
popular language. In 1997 biologists together with
genetic and medical specialists of Roslin
University in Scotland managed to produce the
cloned sheep Dolly and officially publicized its
existence. [ 2 ] Since those times the idea of
cloning became a subject of intense interest and
permanent discussions all around the world. For
the last decade it remains to be one of the most
emotional and controv...

Introduction To Evolution What is Evolution?
Evolution is the process by which all living
things have developed from primitive organisms
through changes occurring over billions of years,
a process that includes all animals and plants.
Exactly how evolution occurs is still a matter of
debate, but there are many different theories and
that it occurs is a scientific fact. Biologists
agree that all living things come through a long
history of changes shaped by physical and chemical
processes that ar...

Wilmut And Dr Unicellular Organisms

The biological definition of a clone is an
organism that has the same genetic information as
another organism or organisms. Thus, an
elaboration on the history, techniques, ethics,
and reasons for researching the technology of
cloning is necessary. A clone is an organism
derived asexually from a single individual by
cuttings, bulbs, tubers, fission, or
parthenogenesis reproduction. Parthenogenesis
reproduction is the development of an organism
from an unfertilized ovum, seed or spore. Hence,

Crown Of Thorns Coral Reefs

Coral reefs are among the most varied and
productive communities on Earth. They are found in
the warm, clear, shallow waters of tropical oceans
worldwide. Reefs have functions from providing
food and shelter to fish and invertebrates to
protecting the shore from erosion. Unfortunately,
as our understanding of corals and coral reefs
increases, it becomes apparent that the effects of
the human population on these communities may be
increasing as well. Reef-building (or hermatypic)
corals are of th...

Could icy moons of giant planets, such as Europa
and Callisto, provide possible habitable
environments for living organisms? Until such task
is actually accomplished, scientists and
researchers all over our world will forever be
trying to find life in other parts of both our
galaxy, and the Universe. Such fascination with
extraterrestrial life has been brought to somewhat

98 Question What are the effects of varying pH
levels on Rhizobium bacteria, and can a pH
resistant Rhizobium culture be grown? Hypothesis
Alterations of the balanced habitat such as the
change of pH levels can drastically alter the life
of bacteria and can directly affect chemical
reactions of enzymes released by the bacteria.
Using this information the change in pH will have

Million Years Ago Mass Extinction

Earth probably began Extinction Introduction Earth
probably began about 4. 5 billion years ago. A
history of this life on Earth is recorded in
fossil remains and traces of past life. It is a
record of evolution for both life and the planet.
Life and the planet have co-evolved, with life
causing changes to the planet which in turn drive
changes in life. The Fossil Record A history of
these changes is recorded in the layers or strata
of rock laid down over the millions of years, and

biologists learn about life on Earth in all its

being discovered the search for life elsewhere
grows more steadily pressing. We have discovered
organisms on the Earth that seem tenacious and

All living organisms are composed of cells. A cell
is a small, membrane-bound compartment that
contains all the chemicals and molecules that help
support an organisms life. An understanding of the
structure of cells is one of the first steps in
comprehending the complex cellular interactions
that direct and produce life. Cells can be thought
of as building blocks of organisms. Some organisms
are composed of a single cell. Others, like
ourselves, are composed of millions of cells that

Paleo Ecological Reconstruction Paleo Ecological Evidence Organisms

One of the principal objectives of geologists
studying sedimentary rocks is the reconstruction
of the environment in which the rocks were
deposited. Correct reconstruction may result in
the discovery of oilfields, deposits of salts, or
base metals, and provide insight to our earths
past. As evidence to ancient environments the
geologist has the structures, textures, and
composition of the grains that make up the
sediments, and the fossils preserved in them.
Organisms are far more sensitive to, a...

Darwin Theory Earth Surface

Evolution, a process of change through time, is
what links together the enormous diversity of the
living world. A lot of evidence is present that
indicates that the earth has had a very long
history and that all living things arose in the
course of that history from earlier, more simpler
forms. In other words, all species have descended
from other species and all living things share
common ancestors in the past. Basically, organisms
are what they are because of their history. Today
there are man...
